Hi guys ordering my 2018 A5 sport back soon and plan to do an exhaust immediately, my question is, on the A5, is there a place to unbolt the stock catback, I plan to do a muffler and resonater delete, and want to be able to put the stock Catback on the car when the lease is up, without any welding or cutting at all. Thank you, new to the forum so sorry if there is another thread about this somewhere. Thatnks again.
